असमानता \(7-2x\geq -9\) का हल अंतराल रूप में क्या है?
What is the interval form of the solution of \(7-2x\geq -9\)?
Explanation opens after your attempt
D. (\(-\infty,8]\)
Concept
From \(-2x\geq -16\), we get \(x\leq 8\). Since equality is included, (8) gets a closed bracket.
Why this answer is correct
The correct answer is D. (\(-\infty,8]\). From \(-2x\geq -16\), we get \(x\leq 8\). Since equality is included, (8) gets a closed bracket.
Exam Tip
\(-2x\geq -16\) से \(x\leq 8\) मिलता है। बराबरी शामिल होने से (8) पर बंद कोष्ठक लगेगा।
